HENRY S. NUNAMAKER, OF CANTON, OHIO, ASSIGNOR TO THE V. L. NEY HAY TOOL COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO.

HAY-CARRIER.

Application filed February 28, 1919.

To all whom it may camera Be it known that I, HENRY S. NUNAMAKER, a cltizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful I-Iay Carrier, of which the following is a specification. v I

The invention relates to hay carriers and has more especial reference to cross draft hay carriers or that class of carriers in which the elevating rope leads from the carrier in a direction substantially at a right angle to the track along which the carrier is adapted to move.

The object of the invention is to provide a hay carrier of the character mentioned with a latch that will automatically trip when the desired load is attached to the elevating rope, locking the rope against movement and locking the sheave against rotation.

A further object is to provide a hay carrier of this character in which the sheave is locked against rotation ratherthan merely gripping the rope as is common in hay carriers of the usual construction.

Another object is to provide a hay carrler of this character in which the latch is released by the operation of the elevating rope, holding the parts in position to allow the rotation of the sheave.

With these objects in view the inventlon consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawmgs,

and particularly pointed out in the ap-' pended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claims, without departing from the spirit- Specification of Letters Patent.

Serial No. 279,720.

Fig. 3, a section on the line 33, Fig. 1, with one end of the truck frame broken away;

Fig. 4, a detail perspective view of the latch;

Fig. 5, a detail perspective view of the rope grip; and

Fig. 6, a side elevation upon a smaller scale of the carrier showing the rope fall.

A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals of reference indicate corresponding parts throughout the several views.

The track 1 upon which the carrier is adapted to run may be of any suitable or well known form and is suspended from any substantial support such as the rafters of a barn. The main frame of the carrier is suspended upon the truck frame 2, which is provided at its ends with the rotatably mounted traveling wheels 3 adapted to run upon the track.

The main carrier frame is formed of two sides 4 and 5, preferably stamped from sheet metal which are connected to each other and held in spaced relation. Strips 6 are attached to the side frames in any approved manner and extend upwardly beyond the frames, the upper extremities of said strips being connect-ed to the head 7 which is carried in the truck frame 2. In this way it will be seen that the carrier with its load is suspended from four traveling wheels, two being arranged at the front and two at the rear. In the lower portion of the main frame and at a point substantially be low the center of the track is located the main sheave axle 8, which extends transversely from one side frame to the other and upon which is rotatably mounted the main sheave 9. This sheave is preferably of considerable diameter to lighten the draft as much as possible and facilitate the operation of the carrier.

Pivotally connected to the side frames 4 and 5 upon a transverse bearing having its axis at 10 is the rope locking lever 11 comprising two similar spaced members joined together by means of suitable bolts 12 and 13. The rope locking lever extends outwardly to one side of the main frame and is provided with a downwardly depending t n 15* in wh h are carried the l r 14 and 15 mounted upon suitable bolts or their equivalents 16 located through the spaced side members of the rope locking lever. The sheave brake 17 is pivotally mounted upon a suitable axis adjacent the sheave 9, such as the axis 10 of the rope looking lever as illustrated in the drawings.

1 The rope grip 18, preferably comprises an L-shaped member provided with a serrated surface 19 upon the side adjacent the rope and is pivotally mounted between the side frames upon an axis 20 located through the main frames. The free arm of the rope grip is pivoted at 21 to a pair of spaced downwardly depending L-shaped links 22, which links are pivotally connected near their lower extremities to the rope locking lever by means. of the bolt 13.

A stirrup 23 is attached to the lower portions of the links 22 and the stem 24 is slidably located through an aperture 25 in the bottom of the stirrup, said stem being provided with the eye 26 at its lower extremity and with a nut 27 at its upper extremity. A locking pawl 28 is carried upon the upper extremity of the stem 24 and interposed between said pawl and'the bottom of the stirrup is a coil spring 29. A sleeve 30 is 10- cated around the spring andis of suflicient length to contact with the locking pawl 28 when the spring is compressed the necessary amount, thustaking the weight of the load oif of the spring and preventing damage to the spring by undue strain thereon.

'The latch 31 is pivotally connected at 32 to the side frames and comprises the spaced side members 33, each of which is provided with a cut out portion 84 adapted to receive the extremity of the adjacent link 22. Each of the side portions 53 of the latch is provided with the outwardly extending cam .portion 35 having a curved under face 36 and with an outwardly and upwardly inclined rest member 37 arranged toreoeive the notched portion 38 upon the extremity of the adjacent link 22. when the several parts of the carrier are in the unlocked or loading position as shown in Fig. 1. The side members of the latch a e con nected by the horizontally disposed web 39 arranged tobe engaged by the nose of the locking pawl 28 when the parts are in the locked position assumed when the load is being transported along the track.

In reeving the carrier one end of the elevating rope 4:0 is connected to the eye 26. either by knotting or by use of a device such asthe rope clamp 41. Extending from said eye the rope passes downward and through the lifting head or heads of the sling or other hay engaging device, and then upwardly from said hay engaging device and over the main sheave 9 and then outwardly beneath the rope grip l8 andbetween the rollers 14 and 15' upon the rope locking lever. From this point the elevating rope extends downwardly at an angle to the side 77 as the "purlin pulley.

It will be understood that the carrier is arranged to be moved laterally upon the track in the usual manner. The ordinary method of moving a cross draft carrier upon its track is to attach a rope to each side of the carrier, said ropes extending away from the carrier upon each side and in a plane parallel'with the track. One of'these ropes passes over a pulley attached to some portion of the side wall of the barn and a sand bag or other weight is attached to the end of the rope and the other rope passes over a suitable pulley at the other side of the barn and extends downwardly to a suitable location. This latter rope is the conveyer rope which is used to move the hay carrier. the sand bag upon the other rope acting as a counter-Weight to move the carrier Lek when the conveyer rope is released. is' the usual arrangement of co veyer ropes and has no relation to this invention except that some means must be provided for moving the carrier upon the track.

The operation of a hay carrier embodying the invention is as follows: The parts being in the loading position as illustrated in Fig. 1 it will be noted that the links 22 are in the upper position, resting upon the rest portion 37 of the latch holding the rope locking lever in the raised position and maintaining the rope grip in unlocked po sition so that the fall of the elevating rope maybe brought down to the point or" attachment of the load. When the load is attached and the elevatingteam. which is attached to the free end of the elevating rope, is driven forward drawing the elevating rope forwardly, the load will be raised toward the carrier, the angle at which the elevating rope is located, from the main sheave of the carrier to the purlin pulley, causing the rope locking lever 11 to be held in the upward or unlocked position allowing the main sheave to rotate. the load has been carried up to the carrier and the elevating team stopped the weight of the load will be sufficient to cause the parts to be pulled down-into the position shown in Fig. 2, kicking the latch out of engagement with the extremities of the L-shaped links 22 and compressing the spring 29, allowingthe locking pawl 28 to engage the under surface of the horizontal bar or web 39 looking the parts in this position. It will be noted that when the parts are in this position the rope grip 18 is held in tight engagement with the rope, pressing the rope firmly against the brake 17 and holding the brake tightly against the main sheave; thus locking the sheave against rotation and preventing any movement of the elevating rope.

It will thus be seen that instead of merely locking the rope as is usual in hay carriers, the main sheave itself is locked against rotation. The load will thus be sustained dur ing the travel of the carrier along the track to the place of discharge of the load and in fact until the carrier is returned in the usual manner to the loading point. The shift or conveyer rope is then operated to move the carrier along the track until it reaches the proper position over the mow. The sling or fork is then tripped in the usual manner allowing the hay to drop into the mow and the shift or conveyer ro e is operated in the opposite direction, moving the carrier back along the track to the initial or loading point. The elevating rope is then given a quick pull, straightening the said rope from the main sheave to the purlin pulley, raising the rope locking lever and moving the parts into the unlocked position as shown in Fig. 1. The rope grip is thus maintained in the unlocked position and the brake is released, allowing the main sheave to be rotated so that the fall of the elevating rope may be brought down to the point of attachment of the load.

It should be noted that as the rope looking lever is raised, raising the links 22 and disengaging the nose of the locking pawl 28 from the horizontal web 39 of the latch the upper edges of the inturned portions of the L-shaped links 22 will engage the curved under faces 36 of the cam portions 35 of the latch, moving the latch into the position shown in Fig. 1 bringing the rest portions 37 of the latch beneath and in engagement with the under edges of the intake portions of the L-shaped links 22. By this construction a positive latch is provided which is automatically operated to hold the parts in the loading position as illustrated in Fig. 1 by the movement of the L-shaped links.

I claim:

1. A hay carrier provided with a main sheave, an elevating rope connected to said carrier and passing over the sheave and forming a fall and extending away from the sheave at an angle, means for automatically locking the sheave against rotation when a predetermined weight is placed upon the fall of the elevating rope and means for releasing said sheave when a pull is exerted upon the elevating rope.
